The present disclosure relates to a method for festooning a power cable while deploying it in a deployment site comprising a rail having a start and an end, the method comprising the steps of: providing the cable with a plurality of cable holders slidably movable along the rail, each two consecutive holders being spaced at a holder predetermined distance on the cable; providing a festooning apparatus after the start of the rail, the festooning apparatus comprising a lowering device movable between a raised position and a lowered position; deploying the cable along the rail by repeating the following sub-steps: engaging on the rail one holder after the other and moving them thereon; when one holder oversteps the festooning apparatus, operating the festooning apparatus to move the lowering device from the raised position towards the lowered position, thus engaging the cable at a point between two consecutive holders; when the lowering device reaches the lowered position, obtaining a sagged portion of cable and a shortening of the holder predetermined distance; operating the festooning apparatus to move the lowering device from the lowered position towards the raised position, thus disengaging it from the cable; fixing the shortened holder predetermined distance between two consecutive holders at each side of the sagged cable portion; and advancing the sagged cable portion along the rail.

A pipe hanging system for aligned installation of a pipe from a support system without the use of external measuring devices incudes a hanger assembly having one or more hanger members each having a cradle dimensioned to receive at least a portion of the pipe in a supported relation therein. The hanger members include a plurality of alignment marks disposed on and visible along at least a portion of the hanger member to facilitate positioning the hanger member relative to the support members without the use of external measuring devices. A mounting assembly to mount each hanger member to one of the plurality of support members in an aligned orientation, wherein an aligned orientation is at least partially defined by a portion of the cradle disposed a predetermined distance from a preselected portion of the support member onto which the hanger member is mounted.

A connection device for suspending a monorail beam includes a top anchor integrated with or attachable to a roof bolt and a clamping device for connection to the monorail beam. The clamping device has a housing attachable to the monorail beam. The housing includes a central recess with an opening configured such that the top anchor is movable into and out of the central recess along a first axis through the opening. The clamping device has a plurality of locking members radially movable into and out of the central recess with respect to the first axis between an inner locking position in which the locking members prevent the top anchor from moving out of the central recess, and an outer open position in which the top anchor is free to move past the locking members, each respective locking member being provided in a respective radial guide recess of the housing.

A suspension assembly (10) comprises a support member (12) for supporting an article, an elongate substantially flat strip (14), and a securing arrangement (16). The support member (12) defines an opening (24) through which the strip (14) can be Inserted. The strip (14) defines a plurality of apertures (26). The securing arrangement (16) includes a securing member (18) receivable through a selected one of the apertures (26) in the strip (14) to secure the support member (12) to the strip (14).

A reaming and self-rotating anchor rod includes a rod body, a drill bit, a connecting member, a tray, and a nut. One end the connecting member is snap-fixed to the tail part of the rod body, the other end of the connecting member is connected to an anchor rod bolter. The rod body has an annular protrusion at its middle part to block powder so that the powder fills up the clearance between the rod body and the coal mass. The drill bit has female threads and can be screwed into the front part of the rod body, and the drill bit has baffle pawls and spiral grooves on its side surface.
